Mouthfeel: Medium body and very thin for a RIS. Although i get a touch of the alcohol, it goes down too easy. I expect a beer in this style to be viscous and chewy, and this doesnt give me that satisfaction. Also a bit of bitterness on the finish

Overall: I think this beer is overrated to be quite honest with you. It has a decent amount of the roasted malt, chocolate qualities you want in an imperial stout, but its not up there with Founders IS, Expedition, Ten Fidy, or even Brooklyn Black Chocolate Stout in my opinion. I found the mouthfeel to be lacking as well as its very thin and not as luscious as a beer in this style should be. Still a solid RIS and should cellar well

A: pitch black, with an attractive, though quickly disappearing dark tan headS: strong dark coffee dominates, with hints of bitter chocolate & charred woodT: definitely boozy, in a good way. More strong coffee, charred red meat, with virtually no sweetness to speak ofM: a bit thin, with pleasant carbonation. It coats the tastebuds, lingering there like an old friendO: definitely a stellar example of the style, but to be fair, it can't really compare to the bigger & bolder BA & adjunct brethren.
